Application filed February 9, 1920. Serial-No. 357,453.

To all whom it may concern:

Be it known that I, HENRY F. Drnnons, a citizen of the United States, and a resident of Algonquin, in the county of McHenry and State f Illinois, have invented certain new and useful Improvements in Stucco Foundations for Building-Walls; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the characters of reference marked there on, which form a part of this specification.

This invention relates to improvements in exterior face finishing for building walls which comprises an outer cementitious material and an inner structure'comprising part of the wall which is formed toprovidelan anchor for the finishing face, the construction of the inner part of the wall having known undercut grooves or recesses to'receive portions of the cementitious material in an interlocking fashion, to hold the facing layer thereon. T hesewall finishings are usually known by the term stucco finish.

The invention relates more particularly to a stucco wall finish of this character which is adapted to be applied to oldbuildings, and when applied to the wall the markings on the finished surface may be of any suit.- able character. V

The principal object of the invention is to provide a peculiar form of lath and the manner of its use in an ordinary overlapped weatherboard siding wall which. is the lath being adapted to be applied to the exposed'or weather faces of the overlapped sidings of a wall of an old building, so" as to produce a plain or substantially plain foundation for the stucco or finishing layer, and also provide in a novel way interlockin grooves or recesses in the wall structure hy which to anchor the stucco finishing layer, which latter, as before stated, may be exteriorly finished or designed to suit the'artistic taste of the builder.

A further object of the invention is to so adapt a novel form of lathing to'the overlapped covering members of abuildingwall as to produce in a very simple way a plain face to receive thestucco material, and undercut grooves to interlock or anchor the material with the wall'structure.

' Other objects ofthe invention are to-im prove, simplify, and reducethe cost of the application of a stucco facing finishfor old buildingsfand the inventionconsists in the combination and "arrangements of the parts shown inthe drawings and described in the specification, and is pointed out in theap pended claims, In the drawings is shown of my invention wherein I Figure 1 is a fragmentary face view show-f ing in different planes the olc'loverla'pping s'idlngjof a building wall,'the' lathingappli'ed thereto, 'and'the finished wall.

The said lath'strips 12* are leach] Flg gi 3 emen section at a an overlapped siding that made wider at one edge than at its other, being thus taperedso that when the nar- V rower edge 13 of alath'strip is applied over the butt or wider edge of a siding board 11, with said narrower edgesubstantially flush with the square wider edgeof said siding board. 'ljhe angle of the taper of the lath 1ng strip is such as to cause the outer face of the lathing strip, when so applied, to be substantially parallel to the plane'of the'studding 10, and with the outer faces-of the la tlf1 ing strips disposed in the same plane. [The said lathi'ng str1p's'l2 are of less widthcthan the weather exposed faces" of the" siding boards-so that the siding boards there is produced between the lower wider'edges 14, 14: of the lathing adjacentbutt edges of the -sid-- strips and the ing boards horizontal grooves 15. The angle of transverse taper of the lathing stripslQ is such that when a number'thereo'fare applied to adjacent siding boards the outer faces of the said lathing strips of the compound wall structure thus formed lie in a plane substantially parallel to the plane of the adjacent faces of the studding 10, interrupted only by the grooves 1 5.

when' applied. and, nailed to so-C'alled stucco j material that,is' ,.lai'df in proper thickness over the" compound Wall structure formed by the overlapped siding boards and the overlapped lathing strips, and the grooves 15 receive aportion of this, material to form anchoring'ribs 17 that interlock with the walls of the grooves 15 to hold the finishing surface of the stucco wall I in place.- It is desirable, in order to produce and maintain a good'interlocking connection between the facing or stucco layer 16 and the wall structure described that, at least, one of the walls of each togive an undercut efiect to the groove, and for this purpose the wider side margins 14 of the lathing strips are so beveled. Fig. 3 indicates a method by which these tapered and beveled strips may be readily produced from a rectangular strip or board.

In practice, a piece of lumber of proper dimensions may be sawed into a number of parts of the dimension shown in Fig. 3. The first cut of the saw will be at an angle to the plane of the board to produce an angle edge 14, which a ears at the thicker l side of the lath strip.

To produce this taper, the boardmay be applied to the saw on a table that is tilted at the proper angle. Thereafter the table will remain at this angle. while successive strips are sawed from the board,'each strip being of the cross section shown in Fig. 3. Thereafter the strip is adjusted on the table so as to ripit along the diagonal line 18, shown in Fig.3,which extends from one side margin to the other of the strip so as to produce two lathing strips 12 of the triangular cross section indicated in, Fig. 3 and shown in Figs. 2 and 4, the finished lathing strip being tapered from edge to edge, so as to fit the taper of the siding boards and angled or beveled along its wider edge 14 to produce theundercut effect in the groove 15. The stucco layer 16 of the wall may be marked or decorated before the plastice material thereof hardens so as to simulate a pebble dash or concrete wall or to otherwise ornament thefacing surface of the wall.

From what has been hereinbeforestated, it will be apparent that the ordinary board wall of an old building,

may, by the very simple and inexpensive method disclosed, be converted into a wall having a stucco facing that may be made to closely resemble a block wall or concrete block wall or may be given any other ornamentation desired. It will also be observed that the wall finish may be produced bythe use of inex pensive materials, the wider or butt edges of theold siding boards constituting parts of the grooves 15 to thereby hold the finish ing layers 16 in place. It will also be observed that this effect is produced without greatly increasing the thickness of the wall structure as a whole inasmuch as the outer faces'of the lathing strips do not extend substantially beyond the outermost corners of groove 15 be beveled,

weather the butt'edges of the siding boardsl Practically, therefore, the only thickness added to the wall structure is that due to the thickness of the finishing layer 16 itself.

It will, furthermore, be observed that the structure disclosed, While strong and compact, is a durable one, readily applied, and very economical in respect of material and labor to construct it. In practice, the said lathing strips may bemade of any suitable length, as, for instance, the length of an ordinary wall lath and the width of the strips will depend on the weather exposed faces of the siding boards 11.

I claim as my invention:

1. A substantially wedge-shaped lath strip adapted for application to and cooperation with wall weather-boarding arranged in overlapped relation, to form retaining grooves therebetween, said strip being providedwith a face adapted to be positioned upon said weather-boarding, an outer face, and a third face which is narrower than either of the two other faces, substantially as described. I

2. The combination with a building wall including elements arranged in overlapping relation, each having an outer faceand a face, of a strip positioned upon the outer face of each element and provided with an upwardly and spaced from the downwardly facing edge of the element above, whereby to form agroove therebetween, and cementitious material-covering said elements and strips and filling said grooves. 4 i

3. The combination with a building wall including elements arranged in overlapping and inclined relation, each presenting an outer face and a downwardly facing edge lying in a plane substantially at rightangles to said face, of a strip having an inner face secured to the inclined outerface of each element and provided with an upwardly facing edge lying in a plane at. an obtuse angle to the inner face of the strip and opposed to and spaced from'the downwardly facingedge of the element above, whereby to form, between said strip and element, a groove whichis wider at the bottom than at the :top, and ceinentitious material covering said elements and grooves.

. a. The combination with a building wall angle wh ch is less thanthe angle formed facing edge which is opposed to with the outer face thereof, an

strip and filling said from theexposed edge of the and filling the spaces therebetween.

5. The combination with a building wall including a support and elements arranged in overlapping relation on said support and presenting an outer face inclined with respect to the plane of said support, and a downwardly facing edge at an angle to said outer face, of a strip of substantially triangular cross-sectional configuration posi tioned upon each element and provided with an edge which is opposed to and spaced from the downwardly facing edge of the adjacent element, the inner face of said strip conformin gto the otuer face of the element upon which it rests, while the outer face of the strip is in substantial parallelism to the plane of saidsupport, and cementitious material covering said elements andstrips and filling the spaces therebetween, substantially as described.

6. The method of providing a finish fora wall made up ofweather-boarding arranged in overlapping relation on a support, which consists in positioning lathing strips on said weather-boarding so as to form sidewise opening strips, and thereafter applying cementitious material to said'wall to coverthe weatherboarding and strips and fill said grooves, substantially as described. 7

In witness whereof I claim the foregoing as my invention, I hereunto append my siggrooves between the boarding and o nature at Algonquin, Illinois, this 6th day of February, 1920.
